I run the landing gear up to find the upper limit, bring it back down about 1/4", and then put a wrap of red tape around the inner leg so that I have a reference to avoid hitting the stop and blowing the fuse.
Besides blowing the fuse, you risk damaging the gears when you reach the limits, and replacing the gear set in the landing gear is NOT fun.
